THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 414,260, dated November5, 1889.

Application filed February 7, 1889. Serial No. 298,976. (No model.)

To all whom it may concern.-

Be it known that I, ALLEN V. SMITH, a citizen of the United States,residing at Canton, in the county of Stark and State of Ohio, haveinvented certain new and useful Improvements in Thin-Couplings; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, in which Figure 1 is an isometricalview. Fig. 2 is a sectional view. Fig. 3 is a detached view of theshackle. Fig. 4 is a detached view of the yoke. Fig. 5 is a detachedview of the connecting-bolt. Fig. 6 is a detached view of a portion ofthill-iron, showing eye. Fig. 7 is a detached view of the set-screw.

The present invention has relation to thillcouplings; and its natureconsists in the different parts and combination of parts hereinafterdescribed, and particularly pointed out in the claims.

Similar letters of reference indicate corresponding parts in all thefigures of the draw lugs.

In the accompanying drawings, A represents the shackle, which isconstructed in the ordinary manner, and is prox ided with the ordinaryclip for attaching the shackle to the axle of a vehicle. The yoke B issubstantially of the form shown in the drawings, and is attached asillustrated in Figs. 1 and 2. This yoke is provided with the angularrecess a, which is for the purpose of receiving the head Z) of the bolt0. It will be seen that the recess ais to correspond in form with theboltdrawings the set-screw D is shown pointed,

but the same object can be accomplished by means of a blunt-endedset-screw. The 0bj'ect and purpose of the setscrew D are to press thethill-iron firmly against the connectingbolt 0, and thereby preventingany rattle, and at the same time preventing the bolt 0 from wearing inthe eye E.

It will be seen that by providing the recess a and seating the head ofthe bolt therein, said bolt will move with the yoke as the thills properare moved up and down at their free ends. The connecting-bolt 0 moves orturns in the apertures (Z' in the shackle A.

It will be seen that any desired number of set-screws may be used andarranged in the yoke B.

It will be seen that the yoke B, together with its set screw or screws,may be located on the top or upper side of the eye E, and the sameobject accomplished.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is

1. The combination of the shackle A, the yoke B, adapted to embrace theshackle, and provided with the angular recess a, adapted to receive thehead of the bolt 0, the thill-iron provided with the eye E, and thepointed setscrewD, substantially as and for the purpose set forth.

2. The combination of the shackle A, the yoke B, provided with theangular recess a, adapted to receive and hold the head of the bolt O,and the set-screw D, adapted to press against the eye E, substantiallyas and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

ALLEN V. SMITH.
